My first blogging platform was Dave Winer’s Radio UserLand. One of Dave’s mantras was: “Own your words.” As the blogosophere became a conversational medium, I saw what that could mean. Radio UserLand did not, at first, support comments. That turned out to be a constraint well worth embracing. When conversation emerged, as it inevitably will in any system of communication, it was a cross-blog affair. I’d quote something from your blog on mine, and discuss it. You’d notice, and perhaps write something on your blog referring back to mine.
I would love to be able to comment on an article or a blog entry by passing a link to a blog entry within my own WordPress instance on WordPress.com. However rendering that ‘feed’ back into the comments section on the originating article/blog page doesn’t seem to be common. At best I think I could drop a permalink into the comments section so people might be tempted to follow the link to my blog. But it’s kind of unfair to an unsuspecting reader to force them to jump and in a sense re-direct to another website just to follow a commentary. So I fully agree there needs to be a pub/sub style way of passing my blog entry by reference back into the comments section of the originating article/blog. Better yet that gives me some ability to amend and edit my poor choice of words the first time I publish a response. Too often silly mistakes get preserved in the ‘amber’ of the comments fields in the back-end MySQL databases of those content management systems housing many online web magazines. So there’s plenty of room for improvement and RSS could easily embrace and extend this style of commenting I think if someone were driven to develop it.
